ABSTRACT:
A metal article is protected from corrosion under prolonged exposure to normal ambient atmospheric conditions which cause such corrosion by coating the metal article with an adherent organic coating which does not exude corrosive acid, which comprises an effective amount of an aromatic amine compound containing a p-phenylenediamine moiety which is not an epoxy crosslinking agent but which is capable of being oxidized in air, an air oxidation product thereof, or a mixture of the amine and air oxidation product for corrosion protection of the metal article, before the coated metal article is placed in contact with such atmospheric conditions which cause such corrosion.
